Native to Mexico, Yellow butterfly vine is a pretty twinning herb which produces
beautiful orchid-like flowers. This evergreen tropical vine is easily trained
on a fence. If left
unsupported, this plant will twine on itself to produce a mounding shrub or
ground-cover. The smooth green leaves are 2 inches long by 1 inch wide.
Bright yellow, 5-petaled orchid-like flowers adorn the plant in spring and
summer. Flowers are about 1 inch across. The common name comed from the
butterfly-like seed pods, turning to brown. The clusters of
showy yellow orchid-shaped flowers appear in spring and again in fall.
